'COILING-MACHINE.

Original application filed February 27, 1904,

To all whom it may concern.-

Be it known that I, MARCELLUS O. LOVEJOY, a citizen of the UnitedStates, residing at Portland, in the county of Cumberland and State ofMaine, have invented an Improvement in Coiling-Machines; and I herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to machines for producing spirals or coils fromcontinuous thin strips or ribbons of the softer metals and their alloys,and it is my purpose to provide a machine which will effect this end inthe most economical and expeditious manner.

My invention consists in a shaft, a former provided with a recess in theend adapted to receive the material and form the successive rings of thecoil or spiral and also with an opening to receive the shaft, meanswhereby the shaft may be prevented from revolving while the otherrevolves, and suitable means for giving the material the requiredtension as it enters the device.

In the mechanism in which I have embodied my invention and which ishereinafter described I have provided for the revolution of the shaft.

In the description of the invention reference is made to the drawings,in which Figure 1 is a side elevation of the shaft and former. Fig. 2 isan end view of the front of the former. Fig. 3 is a side elevation ofthe former. Fig. 4: is an end view of the rear of the former and theholding device. Fig. 5 is a vertical longitudinal section of the formershown in Fig. 2. Fig. 6 is a side elevation of the shaft, former, andcollar. Fig. 7 is an end view of a modification of the collar.

The shaft 04 is of the ordinary construction, journaled, preferably,only at the end where power is applied. The former b has a longitudinalcircular opening 0 sufficiently large to permit the shaft to revolvewithin it. The front end of the former Z) has a recess d concentric withthe center of the opening 0, the

outer side of the recess being formed by the circular shoulder e, fromwhich the recess extends inwardly to the opening 0. The width of therecess 0Z should be equal to the width of the material to be treated. Atsome con- Venient point the wall of the former 6 is slottedSpecification of Letters Patent.

outward from the opening 0 to a width substantially equal to the widthof the material to be treated. The slot 0 thus made may be parallel withthe axis of the shaft or may extend diagonally or at an angle to theshaft; but I prefer that the former be provided with two or more slotsvarying from one another in direction. The wall of the recess (Z oneither side of the entrance of the slot 0 into the recess may beslightly beveled on either side, as shown in Fig. 2. Various means maybe used to hold the former from revolving While left free to slide uponthe shaft. Such means are shown in Fig. 4. As shown in Fig. 4, anopening is made in the side of the former 6, into which is inserted therod h, which at its outer end is so secured as to prevent any revolutionof the former, while at the same time movement longitudinally upon theshaft 0 is permittedas for example, as shown in the drawings in Fig. 4.The outer end may slide between two rods or bars 76 is placed parallelwith the shaft, and to reduce friction the outer end of the rod It maybe provided with a pulley or sleeve Z.

The operation of the device is as follows: A continuous strip of metalof the required uniform width and thickness having been provided, it iscarried or passed through one of the slots 0 in the wall of the former6, choice being made of the slots in accordance with the degree oftension required, the tension being creasing as the angle of the slot 0with the shaft increases. When the end passes through the entrance ofthe slot 0 into the recess (Z, it is seized and held by hand or othermeans and pressed into the recess formedbetween the shaft and theshoulder e and the end then secured to the shaft. This may be effectedbysimply wrapping the end of the ribbon about the shaft, or the shaftmay be slotted, as shown in Fig. l, and the end placed within the slot1), or the end may be secured in the collar, hereinafter described.However secured, in either of these methods the shaft being slowlyrotated draws the ribbon within the recess 03,

thus forming the material into a ring. After two or three revolutions ofthe shaft the grip of the rings of the coil upon the shaft is such thattheir opposition sufiices to keep the other material as it is fed inwithin the recess cl. The desired speed is then given to the shaft.

As the coils are formed the former b gradually retracts until the shafthas been filled, when the spiral already formed may be removed and theprocess repeated.

Instead of pressing the material within the recess either by hand ortool when the operation is commenced, as above stated, a collar f on theshaft at the end opposite to the face of the recess may be used. (SeeFig. 6.) Such collar may be provided with a suitable shoulder to enterthe recess (Z and also with a slot to receive and hold the end of thematerial. The collar may be held to the shaft by a setscrew or may bemade in two parts hinged and fixed upon the shaft by means of a setscrewthrough lips on the free ends or other means which will readily suggestthemselves in such manner that it may be removed speedily when desired.Provision may in such case be made for holding the end of the materialbetween the two parts.

What I claim is 1. The combination of a shaft, a former provided with acircular opening and a circular recess in the end around said opening,means whereby said former is prevented from revolving while free toslide upon the shaft and a passage extending from end to end of saidformer of equal Width with said circular recess, substantially as setforth.

2. The combination of ashaft, a former provided with a circular openingand also a circular recess in the end around the opening, an opening inthe face of said recess connecting with a slot or passage extending tothe rear end of said former and conforming in shape to the material tobe treated and means whereby said former is prevented from revolvingwhile free to slide upon said shaft, substantially as described.

3. The combination of ashaft, a former provided with a circular openingfor the reception of the shaft and with a circular recess in the endthereof around said opening, an opening in the face of said recessextending diagonally rearward through said former and within the wallsthereof of equal width and of a shape conforming to the material to betreated, substantially as described.

In testimony that I claim the foregoing as my invention I have hereuntoset my hand this 10th day of July, A. D. 1905.
